He is correct on all accounts. Come with everything you need to make it work.
I wish I could personally account for how well they work, but I can’t. I like the appearance over other gauges, but in research, had heard nothing bad about them, which verified in my mind that I was ok to go with them.
Are you looking for just the wideband or both? Wayyyy to low for both, and too low for just the wideband. I’m at about as low as I’m willing to go with these right now, and since I just sold my LED tail lights from the Alero and have a car, I can afford to sit on these for a while and wait for someone to offer me what I’m looking for.
I have PM’ed you though.
